CA 2753445
The invention relates to a method for adjusting the pH value and/or for neutralizing acid and/or basic compounds, in particular degradation or decomposition products, as part of the reprocessing and recycling of in particular thermoplastic materials, in the course of which the polymer particles are permanently moved and heated in a reactor, wherein at least one filler is added for neutralization purposes, specifically in a quantity which corresponds at least to the anticipated acid or alkali load.
L'invention concerne un procédé pour ajuster le pH ou encore pour neutraliser des composés acides et/ou basiques, notamment des produits de dégradation ou encore de décomposition, dans le cadre de la production et du recyclage de matières synthétiques, notamment thermoplastiques, au cours desquels les particules polymères sont mises en mouvement et réchauffées en permanence dans un réacteur, au moins une matière de charge étant ajoutée pour la neutralisation et, en fait, dans une quantité qui correspond au moins à la charge acide ou basique attendue.
